Review Meta Analysis
Global variation in the incidence and outcome of emergency medical services witnessed out-of-hospital cardiac arrest: A systematic review and meta-analysis.
After Emergency Medical Services witnessed out-of-hospital cardiac arrest, pooled survival is approximately twice as high in Europe (26%) & Australasia (31%), than in North America (14%).

Etiologies of in-hospital cardiac arrest (IHCA) in general wards may differ from etiologies of out-of-hospital cardiac arrest (OHCA) given the different clinical characteristics of these patient populations. An appreciation for the causes of IHCA may allow the clinician to appropriately target root causes of arrest. ⋯ The most prevalent causes of IHCA among the general wards population are hypoxia, ACS, hypovolemia, arrythmias, infection, heart failure, three of which (arrhythmia, infection, heart failure) are not part of the traditional "H's and T's" of cardiac arrest. Other causes noted in the "H's and T's" of advanced cardiac life support do not appear to be important causes of IHCA.

Review Meta Analysis
Medical futility regarding cardiopulmonary resuscitation in in-hospital cardiac arrests of adult patients: A Systematic Review and Meta-analysis.
For some patients, survival with good neurologic function after cardiopulmonary resuscitation (CPR) is highly unlikely, thus CPR would be considered medically futile. Yet, in clinical practice, there are no well-established criteria, guidelines or measures to determine futility. We aimed to investigate how medical futility for CPR in adult patients is defined, measured, and associated with do-not-resuscitate (DNR) code status as well as to evaluate the predictive value of clinical risk scores through meta-analysis. ⋯ There is no international consensus and a lack of specific definitions of CPR futility in adult patients. Clinical risk scores might aid decision-making when CPR is assumed to be futile. Future studies are needed to assess their clinical value and reliability as a measure of futility regarding CPR.

Review Meta Analysis
Long-term outcomes after out-of-hospital cardiac arrest: A systematic review and meta-analysis.
Long term outcomes after out-of-hospital cardiac arrest (OHCA) are not well understood. This study aimed to evaluate the long-term (1-year and beyond) survival outcomes, including overall survival and survival with favorable neurological status and the quality-of-life (QOL) outcomes, among patients who survived the initial OHCA event (30 days or till hospital discharge). ⋯ Our study found that up to 20.8% of OHCA patients survived to 15-years, and survival was lower in Asia compared to the other regions. Further analysis on the differences in survival between the regions are needed to direct future long-term treatment of OHCA patients.
